Detailed answer

Psoriasis is a chronic autoimmune skin condition that primarily causes red, scaly patches on the skin. Hyperpigmentation, characterized by darkening of the skin, is not considered a direct symptom of psoriasis. However, in some cases, psoriasis lesions may heal and leave behind areas of darkened skin due to post-inflammatory hyperpigmentation. This can occur in individuals with darker skin tones and may be temporary or fade over time. It is important to consult with a healthcare professional to accurately diagnose and manage psoriasis and any associated skin concerns.
